DSL Ports and POTS Splitter Connectors
The 50-pin RJ21X Telco connector labeled DSL Ports 1–24 provides the
2-wire loop interface from each DSL port to the demarcation point. (The
Canadian designation for this connector is CA21A.) The 50-pin RJ21X Telco
connector labeled POTS 1–24 provides the interface with the internal POTS
splitters, if installed.
Table 5 lists the pin assignments for each of these interfaces. Note that Pins 25
and 50 are not used.
